Gaia Ajax Widgets is an ASP.NET Hijax library, meaning you donâ€™t have to write JavaScript at all to use it but can use C#, VB.NET, Iron Python or any other .Net language you wish. Your code will just transform into ECMA 1.5 and XHTML.

Gaia implements most of the ASP.NET 2.0 WebControls like for instance Button, RadioButtonList and DropDownList in addition to some more “advanced” controls like a Ajax Menu, AutoCompleter, Window and DateTimePicker.
